Although damage from electrostatic discharge (ESD) is much less common on these devices than on early CMOS circuits,
normal handling precautions should be taken to avoid exposure to static discharge. Qualification tests are performed to ensure
that these devices can withstand exposure to reasonable levels of static without suffering any permanent damage.
All ESD testing is in conformity with AEC-Q100 Stress Test Qualification for automotive grade integrated circuits. During the
device qualification, ESD stresses were performed for the human body model (HBM), the machine model (MM) and the charge
device model (CDM).
A device is defined as a failure if after exposure to ESD pulses the device no longer meets the device specification. Complete
DC parametric and functional testing is performed per the applicable device specification at room temperature followed by hot
temperature, unless instructed otherwise in the device specification.
